python使用ctypes模块调用windowsapi获取系统版本示例

python使用ctypes模块调用windows api GetVersionEx获取当前系统版本,没有使用python32

复制代码 代码如下:
#!c:/python27/python.exe
#-*- coding:utf-8 -*-

\”通过调用Window API判断当前系统版本\”
# 演示通过ctypes调用windows api函数.
# 作者已经知道python32能够实现相同功能
# 语句末尾加分号，纯属个人习惯
# 仅作部分版本判断，更详细的版本判断推荐系统OSVERSIONINFOEX结构体
